Hi @Extrahdmi ,
I did a bit of research based on what you mentioned and found something that I think could help with what you’re trying to do—creating modular destructible buildings using Geometry Collections in Unreal.
This tutorial from the Epic Games community shows how to build a modular destruction system from scratch:
What’s great about it is that it doesn’t focus on just blowing up a single giant mesh (like most of the videos out there). Instead, it teaches you how to build buildings from individual modular pieces like walls and columns. Each one becomes its own Geometry Collection, and the tutorial also shows how to use Anchor Fields in specific spots ,like the base of support pillars to prevent, the whole thing from collapsing or having debris floating in the air after destruction. It also covers how to set up clustering and tweak the physics settings to make the whole structure more stable, even when you’re combining lots of parts.
In case you want to dig a little deeper, here’s the official Chaos Destruction documentation as well:
https://dev.epicgames.com/documentation/en-us/unreal-engine/chaos-destruction-in-unreal-engine?application_version=5.0
That should give you everything you need to start building modular, realistically destructible structures without the issues you were running into.
Hope it helps!
